Pump Head Assembly Overview
Buy Genuine Titan ED655 Plus Pump Head Replacement Parts
The Titan ED655 Plus Pump Head Assembly contains important fluid-handling components that work with the sprayer's diaphragm pumping system. Its inlet and outlet valve components help regulate the direction of coating movement, while the paint pump block provides the main fluid passage structure for the assembly.
During operation, the pump head must admit coating material, support pressurized delivery and provide the appropriate fluid path during priming and spraying. Worn valve seats, damaged sealing components, debris around valve balls or problems with the prime/spray valve can interfere with these functions.
AllTitanParts lists 16 individual replacement components for this pump head, including 0278242 Inlet Valve Assembly, 0278334 Paint Pump Block, 0555850 Prime/Spray Valve Assembly, 0278241 Ball Cage Seat Assembly, 0093635 Outlet Ball and 0156646 Seal.

How the ED655 Plus Pump Head Supports Sprayer Performance
Coating Intake
The inlet valve assembly admits coating material into the pump's fluid chamber during the intake portion of the pumping cycle.
Fluid Displacement
Movement from the diaphragm pumping system changes chamber volume, allowing coating material to move through the pump head.
Outlet Valve Control
The outlet ball, seat, guide and spring support one-way fluid delivery through the outlet passage.
Priming and Spraying
The prime/spray valve assembly directs fluid through the intended operating path during applicable priming and spraying procedures.
Troubleshooting and Repair
